Added spring-mock as well as H2 for easier unit testing.
Replaced postgres testing by H2 testing. Not using in memomry database to make ony very minor code changes to make the test runnable.
Set a nicer name for h2 test database : jdbc-sync-test
Removed duplicate dependency on mockup.
Merge pull request #1 from adriens/master
